APPARATUS FOR DYElNG SIEGIFICATIONforming part of Letters Patent No. 514,743, dated February 13, 1894.

Application filed November 28, 1892 Qerial No. 453,354. (No model.) 7

To all whom it mwyconcern:

Be it known that I, LEONARD WELDON, of Amsterdam, in the county of Montgomery,in

' the State of New York,-have invented new and ing of an indigo blue color combed or carded wool, usually termed slubbm itconsists in a novel organization of the machine which producesin anovel and economi cal manner two desirable results in the operation of dyeing the 'slubbing, vizz firstit produces a uniform shade on a large quantity of slubbing passed through the dye-liquor, and secondly it obviates the liability of tearing and matting the slubbing and the resultant necessity of recombing the fibers. These improved results I attain by the following construction and combination of parts.-

In the annexed drawings Figure l is a vertical longitudinal section of a dyeing machine embodying my invention. Fig. 2 is aside elevation of the dye-liquor-vat showing the gears by which motion is transmitted to the rollers which carry the slubbin g through said Vat and subsequently express the liquid from said slubbing. Fig. 3 is a front elevation of the reel upon which the spools of slubbings are mounted. Fig. 4 is a plan'view, and Fig. 5 is a vertical transverse section on line as, m, Fig. 2.

Similar letters of reference indicate corre sponding parts.

A represents the vat which contains the dye-liquor with which the slubbing is to be treated. Horizontally across the interior of said vat and below the water-line thereof are extended a series of rollers RR- arranged in pairs with the roller -R- directly over the roller --R. Said rollers are journaled in suitable bearings in the sides of the vat, and the journals of the lower rollers protrude through one side of the vat and have affixed to them suitable gears -f or sprocket-wheels which are made to rotate in unison and in one and the same direction either by intermediate gears or a sprocketchain as shown in Fig. 2 of the drawings.

In order to properly support-the saturated slubbing during its passage through the vat I apply to the lowerrollers -R 'R an endless apron --a' as shown in"Fig.1 of the drawings.

Upon one end of the vat -A I mount suitable brackets h-- to which I pivot a roller -P which is parallel with the rollers RR.. To the top of the opposite end of the vat I rigidly secure brackets h-in roller -P. This lower roller is rotated in unison with the rollers -RR by suitable gears or sprocket-wheels and chains.

-O denotes a rack or standard which is provided with bearings for the spindles of the spools j-;y'' upon which the slubbing to be dyed is wound. The slubbings pass from the said spools over the roller P which guides the slubbings overthe edge of the vat and into the interior thereof where they pass betweenthe rollers RR which carry them lengthwise throughthe "dye-liquor. From thence the slubbings are-carried out of the vat by the squeezing rollers P-P" between which the slubbings pass and by which the liquid is expressed therefrom. The slubbings pass from thence through the usual washing and drying devices.

It will be observed that the described rollers and apron maintain the slubbings in straight parallel strands in their transit from the spools --jj-- through the dye-liquor and to their delivery from the vat, from which they pass in a nearly dry condition.

A plurality of dye-liquor-vats -A with the described guiding, dipping and squeezing rollers may be arranged end to end and in line with each other to pass the slubbings successively through said vatsand thus dip the slubbings in the dye-liquor as often as may be desired.

In order to maintain the dye-liquor at a uniform strength in the vat A--, I employ in connection therewith a tank T- in which to mix and store the dye-liquor preparatory to replenishing the vat A. Said tank is located in a plane above the vat, and a pipe bleadsfrom the tank to the vat and communicates with the interior of the latter below the high water line thereof, and thus prevents the dye-liquor from coming in contact with the air during the transit of said liquor from the tank to the vat. By means of a valve b' connected to the pipe bthe flow of the dye-liquor through said pipe can be controlled at will of the person in charge of the dyeing machine. The receiving end of said pipe is a sufficient distance above the bottom of the tank T- toleave therein the necessary room for the collection of the sediments of the dye-stuif.

To guard against overflow of the-dye-liquor in the vat A- I connect to said vat at a proper-elevation above the rollers R' an overflow pipe cand place in a plane below the vat --A- a receptacle G- through the lower portion of which the pipe -cpasses and from thence rises above said receptacle and terminates in a bowl D- which is in a plane partly above and partly below the high water-line of the vat A. The lower portion of the pipe -c-- which is in the receptacle -C is provided with a discharge nozzle -dand with a valve cby which to open and close said nozzle. To the top edge of the bowl D-- is pivoted a lever Z to one end of which is affixed a float e. The opposite end of said lever is connected by a rod Z' to a suitable lever attached to the valve -c'.

In the operation of the described dyeing machine the partly exhausted and surplus liquor passes from the vat -A through the overflow pipe --c and in case the valve cis closed said liquor rises in the pipe to the bowl D- where it lifts the float -e and thereby causes the lever Z- to open the valve c' which allows the liquor to escape into the receptacle -C- into which it flows until the pipe is relieved of the liquor sufliciently to allow the float to descend, which then closes the valve.

By the employment of the described overflow pipe with its discharge valve and float controlling said valve, the exposure of the overflowing liquor to the air, and the injurious influences of oxygen on said liquor are obviated.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for dyeing slubbing, the

combination, with the dye-liquor vat, of par allel rollers extending across the interior of the vat beneath the water line thereof and arranged in pairs with one directly over the other, an endless apron wholly within the vat and carried on the lower rollers, a rack outside of one end of the vat, spools mounted on said rack and having the slubbings wound upon them, a guide-roller mounted on said end of the vat to conduct the slubbings into the vat and between the apron and overlying rollers, squeezing rolls upon the opposite end of the vat to receive the slubbings from the apron, and gears transmitting rotary motion to the rollers carrying the aforesaid apron as set forth and shown.

2. The combination, with the dye-liquor Vat, of a dye-liquor receptacle located in a plane below said vat, an overflow pipe extending from the vat and through the receptacle and terminating in a bowl extending to atplane partly above and partly below the high waterline of the vat, a discharge nozzle and valve connected to said pipe within the receptacle, and a float in the bowl connected to the valve to operate the same, as set forth.

3. The improved apparatus for dyeing slubbing consisting of the dye-liquor vat A, rollers R R and R R disposed one directly over the other and beneath the water line of the vat, the apron a on the lower rollers, the conducting roller P upon one end of said vat, the squeezing rollers P and P upon the opposite end of the vat, gears transmitting motion to the lower rollers R and P, the dye-liquor preparing tank T located in a plane above the vat, the pipe I) having its receiving end communicating with the tank T a distance above the bottom of said tank to leave on the latter room for sediments, and having its discharge end in the vat A beneath the waterline thereof,

the valve 12' attached to said pipe, the receptacle 0 located in a plane below the vat A, the over-flow pipe 0 extending from said vat through the said receptacle and terminating in the bowl D at an elevation partly above and partly below the high water line of the vat A, the discharge-nozzle 01 connected to the lower portion of the pipe 0 in the receptacle 0, the valve 0' connected to said nozzle, the

lever Z pivoted to the bowl, the float e on one end of said lever, and the rod Z connecting the opposite end of the lever to the valve a, substantially as described and shown.

In testimony whereof I have hereunto signed my name this 9th day of November,
